To all 'whom it m ay concern.' I

Be it known that I, ARTHUR Doissorr, a subject of the King ,of Great Britain, and resident of 58 Savile Park road, Halifam'in the county of Lancaster, England, have invented a certain new and useful tmprovement in Retort-Discharging Apparatus, of Vwhich the following description, together with the accompanying sheets of drawings, is a specification.' v

My invention relates to mechanism for performing the operation of discharging or effectin the Withdrawal of the spent contents o retorts of the vertical or inclined type used in the manufacture of gas, the distillation of shale,'or for like purposes, andy the object of my present invention is the production of said mechanism of such a character as will enable the withdrawalA or discharging ofl any desired and suitable quantity of the spent material, (such as coke when coal gas is being manufactured) Without the possibility of any larger quantity than is desired being at any time permitted to descend by gravity or .otherwise escape from the retort towhich my apparatus 1s applied. I

A further advantagesecured by the einployment of my mechanism in connection with retorts for the manufacture of coal gas, is that the coke extracted is notbroken or granulated to the extent that it is necessary for it to be to enable its discharge to be carried out by devices at present in use.

In'the accompanying sheets of drawings which are illustrative of my invention:-

Figure 1 is a longitudinal sectional eleva,

tion. of apparatus produced in accordance with my invention. Fig. 2 is a cross seetional elevation of certain parts shown by Fig. 1. Figs. 3 and 4 are similar views to F ig. 2 (drawn to a reduced scale) but show certain of the parts in altered positionsas hereinafter described. Fig. ,5 is a perspective view showing two semi-cylindrical drums with one of the end walls of eachllcut away so as to show their formation as here-` Specification of Letters Patent.

other and with alternative forms or shapes of said cutting edges.

A indicates the framework in which the parts are mounted said framework being arranged to be secured to the lower or dis charge orifice B of a retort.

To attain the object ofy my invention I make use of mechanism, in connection with each retort, consisting of a pair of semicylindrical drums or longitudinal segments of hollow cylinders 2 and 3 which for convenience -I call drums, each having an opening in its periphery at one side. I arrange said drums so that their axes are co-incident, one drinn 3 being so much less in diameter and length than the other drum 2 that it will take into and operate within the latter, so that the drum 2 may be freely rotated in one direction, while the drum 3 is rotated in the other direction. The pivotal shafts 4, il of the inner drum 3 are made to take through the hollow pivotal shafts 5, 5a respectively of the outer drum 2 so that by any suitable gearing such as the spur wheel 6 (which may receive its motion by gearing with a spur wheel carried by any prime oi' other motor shaft) motion may be transmitted to the outer druin 2, and by the bevel gear 7 mounted on the other hollow shaft 5 said drum may transmit motion through the bevel gear 7a and the bevel gear 7b, which is fixed upon the shaft 4, to the drum 3, thus while one drum 2 is rotating in one direction theiother drum 3 will rotate in the opposite direction.

In the walls of the framework A bearings 8 and 8El are mounted to support the shafts of the drums 2 and 3, while on the upper l the drums 2 and 3 in order to protect same from contact with the contents of the cavity above. i

Although I have shown spur and bevel gearing as the means for transmittingmotionto the drums 2 and 3, I am aware that ratchet wheel and pawl mechanism,rack and pinion devices or worm and worin wheel mechanism may be made use of for transmitting motion to said drums 2' and 3.

As these pairs of drums are being rotated they will at one time present their open sides to the base of the retort B, as shown by Figs. 1 and 2, so that the material within Said retort B will, by gravity, descend and ice'v e
